PLOW.

SPECIFICATION forming part of Letters Patent No. 437,217, datedSeptember 30, 1890.

Application filed May 17, 1890. Serial No. 352,253. (No model.) I

To all whom it may concern.-

Be it known that I, J AMEsARoHERMARTm, a citizen of the United States,residing at UniontoWn, in the county of Perry and State of Ala- 5 bama,have invented certain new and useful Improvements in Flows; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making apart of this specification, and to the letters of referencemarked thereon.

This invention relates to certain new and useful improvements in plows;and it has for its objects among others to provide an improved plow, tomake the draft lighter, to prevent obstructions underneath the plow, andto otherwise improve upon the prior forms of this class of devices.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure lis a side elevation of my improvedplow with parts broken away. Fig. 2 is a rear end view of the same withthe handles broken ofi. Fig. 3 is a bottom plan of the integral pointand landside detached. Fig. 4; is avertical cross-section through themold-board.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates theplow-point, which is formed integral with the bar A and with a loop 00upon the inner face of said bar, also with a lug b, to which the lowerend of the left-hand handle B is secured by a suitable bolt c, as shownin Figs. 1 and 2. To the inner face of this handle is secured the beam0, which is also secured to the standard D, the lower end of which isfitted in the loop a of the bar, as shown best in Fig. 1. This bringsthe beam in the same vertical plane as or in line with the bar.

E is a vertical rod hooked at its lower end and engaging the loop'a ofthe bar, as shown in Fig. 1, and passed through the mold-board andthrough the beam, and upon its upper end receives a nut d, as shown,thus serving tachably secured thereto the upper portion of v themold-board or colter G, which is formed upon the compound curve. (Shownbest in Fig. 4.)

The right-hand handleH is lined upon both sides near-its lower end bysteel bars f, the right-hand-side one of which extends along under andfollows the contour of the said upper portion of the mold-board or thecolter, and is secured thereto upon its under face, as shown best inFig. 2. The left-hand one of these bars or braces is extended diagonallyacross to the other handle in a sort of Z shape, and has its end securedto the lefthand handle by the same bolt that secures the said handle tothe bar A, as seen in Fig. 2. This leaves no obstruction underneath theplow. This colter may be readily applied or detached when desired byloosening the nuts on the bolts which secure it to its supports.

I is a weed-cutter, preferably of steel, secured upon the landside ofthe plow to the beam and bar A and extending upward upon a curve withits forward edge sharpened'and above the point of the plow, as seen bestin Fig. 1.

In operation, as the plow enters the ground, instead of tearing andbreaking the sod and roots, the cutter will cutthem with much less powerand render the plow easier to operate. This cutter, extending as it doesabove the plow-point, serves to prevent the throwing of the dirt or sodto the left of the plow, and the sod is cut, not broken.

The form of the upper part of the moldboard is important. By it the sodpasses up the inclined plane and strikes the right-angle bulge leadingfrom the lower corner of the hoe to the right-angle curve of themold-board, and as it reaches this point the lower corner of the boardbeing concave lightens the draft and breaks the sod, and the rise andtwist of the board puts it on the bed in a pulverized condition.

The several features above outlined combined unite to make a plow thatfrom practical tests has proved a most efticient agricultural implementand one that will run with less power than those of other constructions.What I claim as new is 1. In a plow, the combination, with thplow-point, the standard D, and the moldboard, of the beam, the handles,the steel bars f, secured to the lower end of one of the handles, andone of said bars secured to the inner face of the mold-board and theother to the other handle, and the brace F, arranged angularly andconnecting the mold-board and standard, substantially as specified.

2. In a plow, the combination, with the
